icky2000,
I have heard of a lot of issues with DualDiscs. I have not tried using one yet, and I refuse to buy them. Looking through the manual of my Pioneer 588a DVD player (about $150 if you are interested in getting rid of your Oppo like you were thinking) and it says specifically that there are issues with playing DualDiscs, mainly the CD side of it, because it does not conform to the CD specifications or something like that. However I believe I read in the CNET reviews that they tried it, and it worked fine on some of the discs they used. I have read other reviews where they say that the dualdisc is thick, and can get stuck, or scratched as it gets ejected. I would venture to guess that this would be a common occurrence no matter what dvd player you bought, that is if it has a tray. One with a pop top, like on some boomboxes, or travel dvd players may not have such an issue with it, but it may also not play the DVD-A part either. Does that album come in any other format other than dualdisc? If so, maybe look into that instead...
